The device and method use a mapping process to simplify the calculation procedure for intra prediction, to improve coding efficiency. The decoding of encoded data comprises: obtaining an indication indicating whether the intra-prediction mode for a picture block is in a set of most probable modes, MPM, or not; if the indication indicates that the intra prediction mode for the picture block is not in the set of MPMs, generating a mapping relationship between at least one intra prediction mode in the first set of intra prediction modes and at least one intra prediction mode in the set of non-MPMs; decoding the encoded data to obtain an intra prediction mode codeword for the picture block; and obtaining the intra prediction mode for the picture block according to the mapping relationship and the intra prediction mode codeword."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for intra prediction","description":"The present disclosure relates to a method and device of decoding video data.
